We always have to visit the bakeries in Norway and in France. Norway for the yummy sandwiches and pastry. France for ham and cheese croissants and pastry. Some years, we also snack in between and get eggrolls at China or something in Germany. Also always good. Though, sometimes the wait in the China pavillion can be abnormally long given the crowd levels. Last trip, I had the fish and chips at the UK counter service for the first time - awesome!
I've been disappointed in Cantina de San Angel, particularly the guacamole.
